Low load hardness tester complies with
standard
A hardness testing machine designed specifically for low load Brinell tests provides a cost effective means of meeting testing standard EN ISO 6506-1:1999 using the new 2.5mm ball indenter.
A hardness testing machine designed specifically for low load Brinell tests has been launched by Indentec Dedicated to loads from 10 to 187.5kgf, the bench mounted digital system is said to provide a particularly cost effective means of meeting testing standard EN ISO 6506-1:1999 using the new 2.5mm ball indenter

Believed to be the first that a digital Vickers hardness testing machine has been adapted for robotic operation, a system has been configured for a Spanish stainless steel plant.
Simultaneously Vickers test up to twelve surfaces
No less than nineteen different specimens can be supported for hardness testing by a single fixture developed by Indentec.
Indentec expects it to appeal to users in aerospace, foundries, metal forming and other industries where Brinell testing is becoming more general because of the easy preparation and the absence of stress points.
For long term calibration stability, the machine employs proven deadweight technology to measure hardness instead of load cells.
To ensure easy access to test areas that would otherwise be difficult to reach, Brinell tests are made by a ball indenter in a nose mounting.
Several specifications are available, all of them with a built-in measuring microscope.
A unique feature for machines of this capacity, the microscope heightens repeatability by eliminating any need to move the specimen from or around the test table.
The basic system can be progressively automated to minimise dependency on the operator for accurate and reliable testing.
A video camera can be fitted in place of the microscope to project indentations onto a monitor.
In the most advanced form, a computer aided system performs the measuring operation.
Other optional upgrading features include an automatic focus, manual and motorised X-Y tables and software for case depth measurement.
Following trials at Indentec, a machine has been supplied to a Finnish Company for testing a range of aluminium extrusions.
